What happens to the kinetochore during Anaphase 1 of meiosis?
Options
- AIt separates homologous chromosomes
- BIt aligns the bivalent chromosomes on the equatorial plate
- CIt allows microtubules from the opposite poles of the spindle to attach
- DIt disappears
Correct answer
C. It allows microtubules from the opposite poles of the spindle to attach
Step-by-step solution
The final stage of meiotic prophase I is diakinesis. This is marked by terminalisation of chiasmata. : During this phase the chromosomes are fully condensed and the meiotic spindle is assembled to prepare the homologous chromosomes for separation. By the end of diakinesis, the nucleolus disappears and the nuclear envelope also breaks down. Diakinesis represents transition to metaphase Metaphase I: The bivalent chromosomes align on the equatorial plate The microtubules from the opposite poles of the spindle attach t
